John Dalton
He discovered atomic weight and how much differ atoms weightThis today helps use with how we measure and know the weights of many different atoms -
J Plucker
Help largely in the discovery in the electron -
JJ Thomson
Discovered that atoms are not simple solid spheres he discovered the negatively charged electrons that outside of the nucleus of and atom Today he helps use no how electricity, magnets, chemical bonds, and many other things happen -
Ernest Rutherford
He discovered that most atoms are made of space and most matter is made of space, even though he still said there was a nucleus of particles.Today we have learned from his discovery and we know that all atoms have a positively charged nucleuses and a negatively charged outer shell -
Soddy
Observed spontaneous disintegration of radioactive elements into variants he called "isotopes" or totally new elements, discovered "half-life", made initial calculations on energy released during decay. -
Francis William Aston
Observed and found out the mass of different isotopes with spectrograph. -
Neils Bohr
He discovered the electrons orbit the nucleus of the atom. Today this explains why atoms connect to other atoms of how electron pass around many atoms to make electricity -
Enrico Fermi
Conducted the first controlled chain reaction releasing energy from the atoms nucleus.
